How to get an image file and display it on the screen?

This may turn out not to be a Perl question; if so I apologise and
will be grateful for any hints on where to go.

I want to retrieve an image file
(e.g. http://132.206.154.224/fullsize.jpg), and display it in a
particular spot on the screen (Windows at the moment, Linux maybe
later) in its own window which is just large enough to fit it.  I
don't want to invoke the browser or an imaging program to display it.
(Later I might want to do some image processing, and I'll want to
update it every 5-10 seconds).

I've looked in CPAN under Imaging and HTML, but didn't find anything
that looked suitable for displaying the image.  Any suggestions?

Thanks in advance.

Regards,
Allen

Have a look at the LWP module on CPAN.

Have a look at the Tk module on CPAN. I *think* it's been ported to
Windows, but I wouldn't swear by it.

It has.  What Allen wants to do can definitely be done (quite easily) with
a combination of Tk (to display the image) and LWP (to fetch the image).
Note that the current version of Tk (which requires Perl 5.8.x) includes
both Tk::JPEG and Tk::PNG which used to be outside the "core" distribution.
If, though, you have a requirement for 5.6.x, older versions of Tk will
still work; you'll just have to install the two modules separately.

Sounds like you're looking for Win32::GUI or the Tk extensions. Both would
allow you to create a new window, position it anywhere on the screen and
display a picture in it. If you are going to port the program later,
however, you're better off using the Tk module.

Thanks to all for the helpful suggestions.  I knew about TK -- just
didn't think of it in this context.
